Liquid phase cyclohexanol catalytic oxidation to cyclohexanone and epsilon(ε)-caprolactone were studied using aqueous hydrogen peroxide as oxidant and H3PW12O40 (HPA) and H0.5Cs2.5PW12O40 (Cs-salt) as catalysts. The ...

Silica supported chromium is a heterogeneous, active and selective catalyst for the liquid phase oxidation of cyclohexanol by tert-butyl hydroperoxide (TBHP) in the presence or absence of oxygen. It is also active for the ...

Cr/SiO2 mesoporous materials (Cr-MCM-41) were obtained by hydrothermal synthesis. The effect of hydrothermal treatment and calcination temperature on the structure and catalytic behavior of synthesized materials were ...

Amorphous Cr–SiO2 materials were synthesized by the sol–gel method and hydrothermally treated at temperatures between 150 and 220 °C. These materials were used as catalysts for cyclohexanol oxidation with H2O2 as oxidant ...

The aim of this study was to evaluate the effectiveness of 3 solvents (eucalyptol, orange oil, and xylol) on 2 types of gutta-percha (conventional and thermoplastic) and Resilon. Specimens (10 mm diameter × 1 mm thick; n=7 ...
